Research and Scheme Design of Space Positioning System Based on Magnetic Field

With the development of computer technology, human-computer interaction in three-dimensional space has become a trend of human-computer interaction. At the same time, in human-computer interaction, spatial positioning should have the following characteristics and requirements: fast positioning speed, high positioning accuracy, low positioning cost, strong robustness. However, some schemes in the current market are difficult to meet the above requirements at the same time. In addition, a new algorithm is proposed in this paper. The improved gradient descent algorithm is used to realize the accurate positioning of magnetic dipole, the real-time positioning of magnet and the requirement of human-computer interaction.
